Chemical Structure
Description
2,5-Dibromothiazole 4175-78-4 NSC-222407 NSC222407 Thiazole,5-dibromo- (CAS 4175-78-4), molecular formula C3H5Br2NS and molecular weight 246.95 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, bromine substitution, 2,5-Dibromothiazole 4175-78-4 NSC-222407 NSC222407 Thiazole,5-dibromo- is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
